Abstract

The invention discloses a screw loosening agent and a preparing method thereof. According to the technical scheme, the screw loosening agent is mainly prepared by weight by the raw materials which are 70-90 parts of solvent, 5-20 parts of antirust agents, 1-10 parts of corrosion-resistant agents and 1-10 parts of penetrants. The invention further discloses the preparing method of the screw loosening agent. The screw loosening agent has the functions of rust loosening, rust removing, penetrating, lubricating, corrosion resistance and the like, using is convenient, price is reasonable, the problem that traditional disassembling is high in difficulty and bad in effect is solved, manpower and material resources are saved, cost is saved, and great convenience is brought to production and life.

Description

technical field [0001] The invention belongs to the field of fine chemical industry, and specifically relates to a screw loosening agent, in particular to a novel screw loosening agent capable of quickly loosening mechanical fasteners such as rusted bolts and a preparation method thereof, and the prepared screw loosening agent has a loosening effect after use Well, it has the functions of rust loosening, rust prevention, penetration and lubrication and is widely used. Background technique [0002] Screws (fasteners) are indispensable industrial necessities in daily life, ranging from small electronic products and household appliances to large machinery, engineering, bridges, buildings, etc., are inseparable from screws. However, in the daily mechanical maintenance process, it is found that many parts connected by screws are rusted together and are difficult to disassemble. These corrosion problems caused by moisture in the air and various pollutions have brought many disadva...
